Just curious: does anyone know any good, somewhat realistic computer wargames that one could play? I've always been interested in military theory, history, and strategy, so would love to play a wargame where you play as a commander and have to deal with limited intelligence while moving forces around, engaging with an enemy, and (most importantly) dealing with logistics. Paradox games scratch this itch a bit, but I find that they emphasize the "grand" strategy a bit too heavily.

If this doesn't exist: why not? It seems like the Army should spend millions of dollars to give their officers a fun way to get tactical and logistical experience without having to run in-person wargames.
